AUXILIARY RUDDER.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed March 20, 1906. Serial No. 306,989.

To (til whom it may concern:

Be it known that I, WILLIAM M. TAYLOR, a citizen of the United States,and a resident of the county of Mecklenburg and State of Virginia, havemade certain new and useful Improvements in Auxiliary Rudders, of whichthe following is a specification.

My invention is an improvement in auxiliary rudders; and it consists incertain novel constructions and combinations of parts hereinafterdescribed and claimed.

' Referring to the drawings forming a part hereof, Figure 1 is a sideview of a vessel provided with my improved rudder. Fig. 2 is a sectionon the line 2 2 of Fig. 1, and Fig. 3 is a section on the line 3 3 ofFig. 2.

In the present embodiment of my invention the hull A of the vessel isprovided upon each side near the stern thereof with rectangular recessesa.

Frames B, comprising side bars I) and an end bar W, are arranged withinthe recesses, the ends of the side bars being hinged, as at b, to therear ends of the recesses and the end bar connecting the opposite endsof the side bars being extended beyond the sides thereof, as at b Theframes B are approximately half the length of the recesses, and theextended ends 12 of the end bars 6 are connected by a flexibleconnection b with a roller 0, journaled vertically within the hulladjacent to the free end of the frame. The flexible connections I) areof a length to permit the free end of the frame to swing outwardly fromthe hull at an angle of about sixty-five degrees therefrom, and theroller is provided with a weight If, whereby to wind up the flexibleconnection on the roller when the frame is swung inwardly.

Vanes C, corresponding in length to the length of the recesses andprovided at each end with cross-bars 0, having extended ends 0, arepivotally connected by their centers to the ends of the side bars toswing on their vertical axes.

The extended ends of the cross-bars 0 have attached thereto flexibleconnections 0 extending through openings in the hull of the ship andconnected to-rollers a a arranged adjacent to the respective ends of thevanes. Upon the shafts of the forward rollers 11 are secured cams aworking through openings in the side of the hull, whereby to press theadjacent end of the vanes outwardly to assist in opening them. Awater-tight partition a incloses the rollers a a a upon each side of thevessel, and any suitable means may be employed for o crating the saidrollers but since such mec anism forms no part of my invention I havenot deemed it necessary to describe the same.

In operation when it is desired to steer the ship the roller connectedwith the front end of the vane on the corresponding side is rotated toloosen the flexible connection, whereby to permit the front end of thevane to swing outwardly, the cam assisting in starting the vane. l/Vhenit is desired to close the vane, the rear roller a is loosened,permitting the rear end to be swung outwardly by the force of the water,the flexible connection 6 preventing the further outward swinging of theframe. This brings the vane in parallelism with the direction ofmovement of the water, so that there is no resistance thereon, and thevane may be swung inwardly into its recess, retaining it in parallelismwith the side of the hull and with the direction of the force of thewater.

By moving the front end of the vane inward, while the rear end is swungoutward, the vane is so inclined that the force of the water acts uponthe outer side thereof, thus assisting in the closing of the same.

The weight b is designed to keep the flexible connection b wound. uponits roller and is connected by a cord 2), passing over a pulley b to theroller a the cord being wound upon the roller in a direction opposite tothe winding of the flexible connection I).

What I claim is 1. The combination with the hull of a ship having arecess upon each side adjacent to the stern, of a frame comprisingspaced side bars hinged to the rear end of the recess and connected attheir free ends by a cross-bar, the ends of the crossbar extendingbeyond the side bars, said frame being approximately half the length ofthe recess, a fin or vane pivoted by its center on a vertical axis tothe free ends of the side bars of the frame, said vane being provided ateach end with crossbars extending beyond the sides thereof, rollers journa'led within the 'hull adjacent to each end of the fin or vane,flexible connections between the rollers and the ends of the vane, aweight-operated roller journaled in the hull adjacent to the free end ofthe frame, flexible connections of limited length extending between saidroller and the extended ends of the cross-bar, and cams on sundry ofsaid roll ers engaging the ends of the vanes for starting said vanesfrom the recesses.

2, The combination with the hull of the ship, of frames hinged at theirrear ends to the stern thereof, fins pivoted by their centers on avertical axis within the frame, at

the free end thereof, means for limiting the outward movement of thefree ends of the frames with respect to the hull, and means for swingingthe fins on their pivotal connection with the frame whereby to opposesaid fins to the direction of motion of the water or to place them. inparallelism therewith.

3. The combination with the hull of the ship, of vanes in connectiontherewith, frames hinged to the hull and pivoted to the centers of thevanes whereby to permit said 0 therewith, and comprising vanes connectedwith said hull by their centers and mounted to swing on a vertical axis,means for limiting the outward movement of the center of the vanes withrespect to the hull, and means connected with the front and rear ends ofsaid vane to the direction of motion of the water, or to place it inparallelism therewith.

6. The combination with the hull of a ship, of an auxiliary rudder,comprising vanes on each side of the hull near the stern thereof, meansconnecting the centers of the vanes and the hull for retaining saidvanes in a substantially vertical plane, means for limiting the outwardmovement of the center of vane with respect to the hull, and means forswinging the vanes on their connecting means toward and from the hull.
